Breadcrumb navigation script in PHP

[mpjx]

Hi

I've just spent about 4 hours looking in vain for a PHP based breadcrumb
navigation script. There are loads available but they all seem to show the
visitor's current page position within the site folder/file heirarchy.

I'm designing a site with two separate but related areas. Visitors will be
travelling directly back and forth between webpages in the two areas. This
means that any breadcrumb script that shows the page position within the site
heirarchy will not accurately display the route the visitor has taken through
the site.

I'm looking for a script that will do exactly this: show the last (say) 4
pages that the visitor has seen regardles of where they are in the site
structure. I know this is doing exactly the same as the browser 'back' button
but I'd like to offer the facility, in the interests of usability. Theres a
Coldfusion extention 'backward_navigation' that appears to do exactly what I
need but, of course, not available in PHP.

I'd really appreciate it if anyone could point me in the direction of a
suitable script.

Thanks in advance

Breadcrumbs don't really "track" where the user has been, they just show them
where they are in a "hierarchical" structure.

I am probably wrong, but i would think you'd need to use cookies/session
variables to do what you want.
